Two former Parramatta Eels players are accused of harbouring semi-automatic weapons and possessing more than half-a-million dollars in cash after dramatic arrests in Sydney's Centennial Park yesterday.

Driver watches crash unfold around him inside Sydney Harbour Tunnel

A stunned Sydney driver has watched a truck smash into cars around him but incredibly manage to miss his vehicle as a camera on his dashboard filmed.

The bewildered driver dropped expletives as he noticed in his rear vision mirror the crash unfolding in the Sydney Harbour Tunnel yesterday morning.

As soon as the driver, believed to be named Brendon, notices something behind him he lets out a gasp before a screech of tyres can be heard and the truck and another car come crashing through beside him.

"How the f--- did he just miss me?" the stunned driver says.

"Somehow it missed me."

The truck comes to a halt crushed into the driver's side door of the sedan it crashed with, the two drivers appearing to mostly uninjured as they speak to each other through open windows.

Commenters on the Dash Cam Owners Australia Facebook page were quick to quip the driver was the Liberal Party's allegedly fake tradie who has been in the media this week amid claims he was a hired actor paid for the political advertisement he appeared in.

"Bracelet got caught on the steering wheel when he spilled his coffee on himself," the page's administrator replied.
